IMPROVEMENT IN WATER-CLOQET VALVES 4 Specification forming part of Letters Patent N 0. 172,843, dated February 1, 1876; application filed a June 10, 1875. a

full and exact description thereof, reference being had to the accompanying drawing, making part of this specification.

Valves or cocks heretoforemade, in which is used .the ordinary cup-leather piston or diaphragm, having a variable chamber, with water-ways leading thereto from the watersupply to insure theclosing of the valve, all require the use of a very'considerable power to open them, and nearly all are opened against the pressure of the Water.

My invention is intended to relieve the pressureinstantaneously in all cup-leather or diaphragm valves or cocks, so that the slightest efi'ort will enable a .person to open the valve or cook against the heaviest pressure of the water. Y

I will now describe the construction and operation of my improved valve or cook, so as to enable those skilled in the art to make and use my invention, referring by letters to the accompanying drawing, in which Figure 1 is a vertical longitudinal section. Fig. 2 is a vertical cross-section.

In the several figures the same parts are designated by the same letters of reference.

A A is the main body of the valve or cook. B is the induction water-way, leading to the inside of the body .of the valve or cock. 0 is the eduction water-way leading therefrom to the bowl of the closet. D is the cup of the valveor cock, attached to the body of the valve by screwing it in its place at a a. E is the main valve, made hollow or in cup form, with a continuation of a hollow stem, F, and packed in the body of the main valve by means of a cup-leather diaphragm, or packed piston, or their equivalent, at G. it his the seat of the main valve .E. 'Within the'hollow vstem of the'main valve E is arranged a small resting upon the top of thevalvc H, and hold- 4 i Y ing the valve H and valve E firmly to their respective seats. Through the side of the main or cup-formed valve E an opening of small diameter is made at m, to supply water to the chamber of the cup-valve E, slowly or gradually, toinsure the closing of said valve E.

It will be observed that when the valves are at rest the Whole pressure of the water is above the valves, holding them,firmly to their respective seats, and preventing the passage of any water to the bowl of the closet, or

through the eduction-pipe G.

" Now, if the trip-valve H be opened, the out-- let of the trip-valve H being much greater than the hole, aperture or feed m in the side of the main valve E, the water in the body of the valve E is instantaneously discharged through the hollow stem F, and the main valve E is raised from its seat by the pressure of the water. The main valve E is suspended openso long as the trip-valve H remains open, the

water having a free passage through the valve E to the bowl of the closet. As soon as the trip-valve H is closed, which it is instanta' neously upon the release of the hand of the operator, and which closing is efi'ected by filling of the body of the cook or valve E with water through the small aperture m.

The stem of the valves E andH may be constructed in one piece, or solid, and the tripvalve H may be made by cutting away the stem at the point where it passes through the bottom of {the main or cup valve E, and discharging the Water from the body of the valve E into the bowl of the closet through the eduction-pipe O, or any other equivalent form of the trip-valve may be used 5- but I prefer'to discharge the water into the trunk of the closet through the hollow stem of the valve E, as the trip-valve H, substantially as and for the above described. purpose specified. Having fully described my invention what I claim, and desire to secure by Letters Pat- 7 BOYLE ent, is- Witnesses:

The combination of the hollow stem F, valve GEO. STEVENSON,

E, piston G, provided with aperture m, and G. L. ISHAM. l
